There's a wrinkle that makes it worse. Specifically, sites that deliberately invert the power dynamic run into the problem that when women must initiate all communications, you don't get a lot of communications. Tinder avoids this by requiring blind consent from both parties.

What do both have in common? Women feel they have the power. In the case of Tinder, women have the power, don't get spammed, and men devolve to the common case of spammy behavior.

It's the best of both worlds. Or worst, since users tend to be exactly as shallow as their technology allows.
